Referring to Figure 15, Figure 15 is large-scale flat pad manufacture method flow chart of the present invention.The large-scale flat pad manufacture method of built-in water passage protection of the present invention, comprises the steps:
A, the groined type combination support frame with array cooling water channel is set: the supporting frame 12 of groined type structure is set, at the interior supporting frame cooling water channel 16 that arranges of described supporting frame 12;
Wherein, in the interior step that supporting frame cooling water channel 16 is set of described supporting frame 12, comprise:
A1, arrange first cooling group 22: the side brace summer along described groined type supporting frame 12 arranges the first Z-shaped water channel 31, at the interior sustained height of described groined type supporting frame 12, adopts mapping method that the second Z-shaped water channel 32 is set centered by the flat pad plane of symmetry.
That is,, in conjunction with flat pad groined type combination support frame 12 concrete structure sizes, build i.e. the first Z-shaped water channel 31 of cooling water channel that first group of trend be " zigzag ".First this cooling water channel is arranged along supporting frame 12 outward flanges of the groined type combination of ablation in the booster rocket 10 engine gas adfluxions of carrier rocket 1, is guaranteed first cooling support frame 12 outer edge region of the interior current of supporting frame cooling water channel 16; Then supporting frame cooling water channel 16 is turned back and is entered a side bearing beam region of the supporting frame 12 of ablation in same booster rocket 10 engine gas adfluxions, and water flow inside is cooling this side bearing beam region successively; Supporting frame cooling water channel 16 continues subsequently direct puncture forward and crosses the side bearing beam region that core stage motor is concentrated the supporting frame 12 of ablation, and supporting frame cooling water channel 16 water flow inside are cooling this backbar region; After this, supporting frame cooling water channel 16 more forward direct puncture cross a side bearing beam region of the supporting frame 12 of ablation in another booster rocket 10 engine gas adfluxions, the interior current of supporting frame cooling water channel 16 so far complete cooling along journey backbar region.The first Z-shaped water channel 31 based on step a1, at flat pad groined type combination support frame 12 interior sustained heights, take the flat pad plane of symmetry (this plane of symmetry through transmitting in symmetrical centre and umbilical tower 3 planes of symmetry) is the plane of reference, the cooling water channel that adopts mapping method to build second group " zigzag " is the second Z-shaped water channel 32, and the cooling water flow of this cooling water channel is the backbar region of cool stream warp successively.Adopt the second Z-shaped water channel 32 that this backbar of this mapping method builds and corresponding cooled region reality can regard that the first Z-shaped water channel 31 and corresponding cooled region are around due to rocket body axis Rotate 180 degree as, in engineering, simplified structure difficulty, guarantee simultaneously cooled region particularly in booster rocket 10 engine gas adfluxions the groined type combination support frame 12 outer edge region cooling effects of ablation consistent.The first Z-shaped water channel 31 and the second Z-shaped water channel 32 form first cooling group 22 of two " zigzag " cooling water channel array one in co-altitude space, the cooling effect of main completed well font combination supporting frame 12 two parallel support beams.
A2, arrange second cooling group 23: in the adjacent elevation plane of described first cooling group 22, adopt the method for step a1 to arrange second cooling group 23, and make the water (flow) direction of described second cooling group 23 vertical with the water (flow) direction of described first cooling group 22.
On the basis of first cooling group 22 of above-mentioned two " zigzag " cooling water channel, the plane of reference of the Vertical Launch platform plane of symmetry is set, adopt mapping method to build second cooling group 23 of two " zigzag " cooling water channel array two, and will two " zigzags " the second cooling group 23 first cooling group 22 dislocation certain altitude position of two " zigzag " relatively, avoid two " zigzag " second cooling group 23 and " zigzag " first cooling group of 22 formation dead water region interfering with each other above, guarantee does not affect each backbar intensity in flat pad groined type combination support frame 12 at two " zigzag " cooling water channel array cooling water channels of flat pad groined type combination support frame 12 interior structures simultaneously.The two subarray cooling water channels that two " zigzags " second cooling group 23 are respectively the 3rd Z-shaped water channel the 33, the 4th Z-shaped water channel 34.
A3, repetition above-mentioned steps a1 and a2 are to arrange at various height a plurality of spaced described first cooling group 22 and described second cooling group 23.
Based on flat pad groined type combination support frame 12 physical dimensions and first cooling group 22, second cooling group 23, continuation misplaces and builds two " zigzag " cooling water channel arrays of series in short transverse, completes each bolster ablated area in flat pad groined type combination support frame 12 and possesses water cooling safeguard procedures.
B, the flat pad stage body with table top cooling water channel is set: on described groined type combination support frame 12, assemble a minute cooling zone on flat pad stage body 6 table top 14 at described flat pad stage body 6 and set gradually table top cooling water channel 29.
In conjunction with flat pad groined type combination support frame 12 sizes and outer rim trend thereof, near flat pad table top 14, gas-flow is concentrated in ablation first area and in the first cooling zone A, " Contraband " shape array cooling water channel is set.First rely on next-door neighbour's flat pad groined type combination support frame 12 outer rims with the interior Contraband shape water channel 28 that arranges of upper table surface 14, the trunk cooling duct trend of this Contraband shape water channel 28 is parallel to supporting frame 12 outer rims, the side surface of inlet channel Vertical Launch platform, water outlet by table top cooling water channel import and export 35 with being connected of umbilical tower root cooling water channel 21.Then at sustained height second the Contraband shape water channel 28 that be arranged in parallel at a certain distance, after this, continuation equidistantly completes with reference to the method the construction work that near the gas-flow of flat pad table top 14 is concentrated other Contraband shape water channel 28 of ablation the first cooling zone A successively, to inferior interior " Contraband " shape array cooling water channel of the first complete cooling zone A that built.
Take the flat pad plane of symmetry as the plane of reference, adopt mapping method to build " Contraband " shape array cooling water channel in the second cooling zone B in flat pad table top 14.
In conjunction with flat pad groined type combination support frame 12 sizes and outer rim thereof, move towards, continuing to build near the flat pad table top 14 concentrated ablation of gas-flows the 4th regions is " Contraband " shape array cooling water channel in the 4th cooling zone D.Also parallel support frame 12 outer rims are moved towards in the trunk cooling duct of Contraband shape water channel 28, and inlet channel is Vertical Launch platform side surface also, water outlet vertical inlet road, and parallel flat pad table top 14 leads to flat pad outside.After this in " Contraband " shape cooling water channel of next-door neighbour's groined type combination support frame 12 outer rims successively level equidistantly arrange second, third, the Contraband shape water channel 28 such as the fourth class, be built into " Contraband " shape array cooling water channel in the 4th cooling zone D.
Take the flat pad plane of symmetry as the plane of reference, adopt mapping method, " Contraband " shape array cooling water channel based in the 4th cooling zone D builds " Contraband " shape array cooling water channel in the 3rd cooling zone C in flat pad table top 14.
It is symmetrical centre that " Contraband " shape array cooling water channel in flat pad table top 14 interior four cooling zone A, B, C, D totally be take the entrance section center of flat pad core level pod apertures 13, is each other 90 degree Rotational Symmetries, further simplified processing process.
